Has anyone had any experience with trench-less drain replacement? I am referring to the method of pulling new pipe and pushing out the old. Will the pipe hold up to tree roots in the long term as effectively as a traditional PVC pipe? I have very old (and emo) sycamore trees in my front yard and want to disturb the roots as little as possible. However, the roots are destroying my terracotta sewage pipe. This seems like a practical solution.Plus, the price is only a few hundred more than digging a trench. Any thoughts would be greatly appreciated. Thank you.
